PATENTAMT.PATENT OFFICE.
Bekanntlich verbindet sich das Chlorgas mit gut gekühltem Wasser zu einer krystallinischen Verbindung, Chlorhydrat genannt, welches angeblich die Formel Cl2 + 10 H2O besitzt und daher 27,7 pCt. Chlor enthält.As is well known, the chlorine gas combines with well-cooled water to form a crystalline compound, called chlorohydrate, which supposedly has the formula Cl 2 + 10 H 2 O and therefore 27.7 pCt. Contains chlorine.
Erfinder benutzen nun die Eigenschaft des Chlors, dieses Hydrat zu bilden, um das Chlorgas aus Gasgemischen jeder Art abzuscheiden. Das Chlorhydrat soll zur Chlorentwickelung für Chlorirungen, Darstellung von Bleichflüssigkeiten, von Chlorkalk und anderen unterchlorigsauren Salzen Verwendung finden.Inventors now use the property of chlorine to form this hydrate to produce the chlorine gas separated from gas mixtures of any kind. The chlorine hydrate is supposed to develop chlorine for Chlorination, representation of bleaching liquids, of chlorinated lime and other hypochlorous acids Salts are used.
Zur Abscheidung des Chlors und Bildung des Chlorhydrats haben wir folgenden Apparat construirt. Das Gasgemisch wird durch eine gröfsere Anzahl flacher Tröge geleitet, wie sie in Fig. ι im Längsschnitt, Fig. 2 im Querschnitt und Fig. 3 im Grundrifs skizzirt sind. Jeder dieser Tröge wird bis circa zur Hälfte mit Wasser gefüllt, welches durch ein Röhrensystem C, in dem eine stark abgekühlte Chlor-• calciumlösung circulirt, bis nahe zu seinem Gefrierpunkte abgekühlt wird. Die von den Chlorentwicklern herströmenden, gut gekühlten Gase treten bei der abgebildeten Stellung der Hähne durch ein Zweigrohr Z des Chlorzuleitungsrohres, welches unter das Flüssigkeitsniveau W taucht, in den ersten Absorptionstrog ein. Die nicht absorbirten Gase entweichen durch die Röhre H in den zweiten und aus diesem in einen dritten, vierten und fünften Absorptionstrog. Das Chlorgas löst sich zunächst im gekühlten Wasser auf, indem sich ein bei o° gesättigtes Chlorwasser bildet, und hierauf beginnt bei weiterer Zufuhr von Chlor eine successive Abscheidung des gelblichgrünen, krystallinischen Körpers, des Chlorhydrats. Zur Beobachtung und Ueberwachung dieses Processes ist in jeden Kasten ein Glasfenster S eingesetzt, und sobald der ganze Inhält des Troges zu einem breiartigen Magma erstarrt ist und keine sichtbare Absorption des Chlorgases mehr stattfindet, wird dieser Trog durch Oerfnen des Hahnes E und Schliefsen der Hähne Z und H ausgeschaltet. We have constructed the following apparatus for the separation of the chlorine and the formation of the hydrochloride. The gas mixture is passed through a larger number of flat troughs, as they are sketched in Fig. 1 in longitudinal section, Fig. 2 in cross section and Fig. 3 in outline. Each of these troughs is about half filled with water, which is cooled down to near its freezing point through a system of tubes C, in which a strongly cooled chlorine-calcium solution circulates. The well-cooled gases flowing from the chlorine generators enter the first absorption trough through a branch pipe Z of the chlorine feed pipe, which dips below the liquid level W , when the taps are in the position shown. The unabsorbed gases escape through the tube H into the second and from this into a third, fourth and fifth absorption trough. The chlorine gas first dissolves in the cooled water, in that a chlorine water saturated at 0 ° is formed, and then, with further addition of chlorine, a successive separation of the yellowish-green, crystalline body, the hydrochloride, begins. To observe and monitor this process, a glass window S is placed in each box, and as soon as the entire contents of the trough has solidified into a pulpy magma and there is no visible absorption of the chlorine gas, this trough is opened by opening the valve E and closing the valve Z and H switched off.
Zur Erzielung concentrirten Chlorgases wird das Chlorhydrat in denselben Trögen zersetzt. Zunächst wird zu diesem Zwecke die Kühlung unterbrochen und die Kammer durch Oeffhen des Hahnes F mit den Chlorirungsgefäfsen (Chlorkalkkammern etc.) in Verbindung gesetzt. Durch Erwärmen wird nun die Zersetzung des Chlorhydrats eingeleitet, welche unter Entwickelung eines lebhaften Stromes von reinem Chlorgas von statten geht. Die Erwärmung kann nun geschehen durch Einleiten von Dampf durch die Röhre D oder durch Erhitzen des Troges von aufsen vermittelst eines Wasserbades , oder endlich durch quer durch den Kasten gehende Heizröhren. Sobald das Chlor durch Erwärmen bis auf 40 bis 500 fast vollständig ausgetrieben ist, wird der Trog wieder abgekühlt und wieder in den Betrieb eingeschaltet, und zwar zweckmäfsig so, dafs die neu einzuschaltenden Absorptionsgefäfse jeweilen am Ende des Systems angefügt werden.In order to obtain concentrated chlorine gas, the hydrochloride is decomposed in the same troughs. For this purpose the cooling is first interrupted and the chamber is connected to the chlorination vessels (chlorinated lime chambers, etc.) by opening the tap F. The decomposition of the hydrochloride is then initiated by heating, which proceeds with the development of a lively stream of pure chlorine gas. The heating can now be done by introducing steam through the tube D or by heating the trough from the outside by means of a water bath, or finally by heating tubes going across the box. As soon as the chlorine is almost completely expelled by heating up to 40 to 50 0 , the trough is cooled down again and put back into operation, expediently in such a way that the new absorption vessels to be switched on are added at the end of the system.
Die oben beschriebene Methode erlaubt nicht nur, auf billige und zweckmäfsige Weise das Chlor aus Gasgemischen mit Luft und Salzsäure abzuscheiden und zu verwerthen, sondern auch aus Mischungen mit Kohlensäure, was nach den anderen Methoden fast undurchführ-The method described above not only allows, in a cheap and expedient way, that Separate and utilize chlorine from gas mixtures with air and hydrochloric acid, rather also from mixtures with carbon dioxide, which is almost impracticable according to the other methods.
bar ist; denn es verhindert, wie wir gefunden haben, weder Salzsäure noch Kohlensäure die Bildung des Chlorhydrats.is bar; for it prevents, as we have found, neither hydrochloric acid nor carbonic acid Formation of the chlorohydrate.
An Stelle von Wasser von o° lassen sich zur Absorption des Chlors bezw. zur Bildung des Chlorhydrats nach dem beschriebenen Verfahren auch ebenso stark gekühlte wässerige Lösungen von Kochsalz, Glaubersalz, Chlormagnesium, Chlorkalium, Magnesiumsulfat oder verdünnte Salz- oder Schwefelsäure benutzen.Instead of water from o °, you can use the Absorption of the chlorine or for the formation of the chlorohydrate by the process described also strongly chilled aqueous solutions of common salt, Glauber's salt, chlorine magnesium, Use potassium chloride, magnesium sulphate or diluted hydrochloric or sulfuric acid.
